【摘要】：交通基础设施的建设是推进我国国民经济高速发展的关键方式之一,其他各个行业的繁荣发展又与交通行业休戚与共,因此公路行业的建设就变得尤为重要。可是目前,我国现存有关公路的相关标准规范众多,而关于涉路工程的有些部分条文规定存在着不统一的冲突,并且十分庞杂,缺乏具有针对性的专项涉路工程规范。这给地区省市的行政管理部门对涉路工程项目的监管工作带来困难,也给评价机构对涉路工程项目的安全评价工作带来不便,同时也可能会余留涉路项目的安全隐患,从而导致安全事故的发生。为保证涉路工程项目的安全,有必要对涉路工程进行更深层次的研究分析,以此来满足涉路工程安全评价及管理的需求。本文首先梳理了公路安全评价以及各类涉路工程的应用与安全评价的国内外研究现状;然后对涉路工程的定义与分类进行了详细的论述,并分析了涉路工程的跨越式涉路、穿越式涉路、平交与接入式涉路、并行式涉路的安全特性及安全影响因素;其次,根据涉路工程安全评价指标的选取原则与依据,确定了设置要求、技术要求、防护要求为三个子系统,对每个子系统选取若干相关评价指标,建立了涉路工程安全评价指标体系,接着对每一个评价指标做出规定并进行了打分量化处理;再次,在比较分析国内外现有公路安全评价方法的基础之上,选取可拓学物元法作为涉路工程安全评价模型方法,并构造了涉路工程安全评价分析模型;另外,将模型方法运用于涉路工程安全评价实例分析,并验证了可拓物元分析模型的可靠性;最后对涉路工程安全评价的流程做出了详细分析,提出涉路工程动态规划决策模型,并基于本质安全化理论,提出了涉路工程安全的防控措施。本文在可拓学物元模型理论的基础上,以涉路工程的实际项目情况与指标规定的内容的符合等级作为评分依据,通过专家对各评价指标进行评判所得分值作为模型基础数据。运用上述方法对云南某处涉路工程进行安全分析表明:通过基于可拓学物元分析法的涉路工程安全评价法和AHP-模糊综合评价法对比分析,验证其具有有效性,并对评价结果提出了针对性的改善措施及建议,可为相关行政部门提供参考性依据,对涉路工程安全评价工作具有可观的指导意义与实际参考价值。
[Abstract]:The construction of transportation infrastructure is one of the key ways to promote the rapid development of our national economy, and the prosperity and development of other industries are closely related to the transportation industry, so the construction of highway industry becomes particularly important. But at present, there are a lot of relevant standards and norms about highway in our country, and some provisions about road construction have different conflicts, and they are very complicated and lack of specific specifications for road construction. This makes it difficult for the administrative departments of the provinces and cities of the region to supervise the road-related projects, and it also brings inconvenience to the safety evaluation work of the road-related projects by the evaluation agencies, and it may also cause hidden dangers to the safety of the road-related projects. This leads to the occurrence of safety accidents. In order to ensure the safety of road construction projects, it is necessary to carry out deeper research and analysis to meet the needs of safety evaluation and management. This paper firstly combs the research status of highway safety evaluation and the application and safety evaluation of all kinds of road engineering at home and abroad, then discusses the definition and classification of road engineering in detail, and analyzes the leapfrog road of road engineering. The safety characteristics and safety influencing factors of traversing road, parallel crossing and access road, parallel route are discussed. Secondly, according to the selection principle and basis of safety evaluation index, the setting requirements and technical requirements are determined. Protection requirements for three subsystems, each subsystem selected a number of relevant evaluation indicators, established a road engineering safety evaluation index system, and then each evaluation index was specified and quantified; third, On the basis of comparing and analyzing the existing highway safety evaluation methods at home and abroad, the extension matter-element method is selected as the safety evaluation model of road-related engineering, and the safety evaluation model of road-related engineering is constructed. The model method is applied to the example analysis of road safety evaluation, and the reliability of extension matter element analysis model is verified. Finally, the process of road safety evaluation is analyzed in detail, and the decision model of dynamic programming is put forward. Based on the theory of essential safety, the prevention and control measures of road engineering safety are put forward. On the basis of matter-element model theory of extenics, this paper takes the actual project situation of road-related engineering and the content of the index as the basis of scoring, and takes the score obtained by expert evaluation of each evaluation index as the basic data of the model. The safety analysis of a road wading project in Yunnan province shows that the safety evaluation method based on extension matter-element analysis and the AHP- fuzzy comprehensive evaluation method are proved to be effective. The corresponding improvement measures and suggestions are put forward, which can provide reference basis for relevant administrative departments, and have considerable guiding significance and practical reference value for the safety evaluation of road-related engineering.
